Natchez Shooter's Supply has 30RAR 150gr Core-Lokt on sale for $16.99 and there is a $5.00 per box cash rebate from Big Green, which makes it $11.99 per 20...might be a good source of brass at least, at that price...

Yep...you can make quite the little screamer out of this thing, and there are untold numbers of .308 bullets to choose from if you reload. If Big Dumb Green had deigned to show the least bit of support for the platform and the cartridge after introducing them, they could've had a winner on their hands, even with the somewhat proprietary nature of the upper (so, sell complete uppers, doofus!)...
